10 dhur in square feet is 680.625 sq ft on the Patna and Arrah scale, where 1 dhur (धुर) = 68.0625 sq ft. Bihar does not have one dhur size, though. In Hajipur and Muzaffarpur 10 dhur is 950.625 sq ft, in Chhapra it is 871.2 sq ft and in Bettiah it is 1,633.5 sq ft.
Why the dhur changes from district to district
In Bihar the chain is always the same: 20 dhur make 1 katha and 20 katha make 1 bigha. A dhur is further split into 20 dhurki, though dhurki is rarely used now. What changes is the size of the katha. When the katha is bigger, each of its 20 dhur is bigger too. All the values below are commonly used local figures, not values from a government notification.

Dhur to square feet for common counts
People usually search for a small number of dhur, because house plots in Bihar towns are sold as "5 dhur", "10 dhur" or "1 katha 5 dhur". This table gives each count for all four regional scales.

How to convert dhur to square feet
Square feet = dhur × the local dhur size
Example from Patna: a plot is 12 dhur. 12 × 68.0625 = 816.75 sq ft.
Most papers mix katha and dhur, for example "2 katha 10 dhur". Turn the katha into dhur first (2 katha = 40 dhur), add the 10, and multiply 50 dhur by the local size:
- Patna and Arrah: 3,403.125 sq ft
- Hajipur and Muzaffarpur: 4,753.125 sq ft
- Chhapra: 4,356 sq ft
- Bettiah: 8,167.5 sq ft
The same words give plots that differ by more than double. That is why you must know which scale the village follows.

Tips for reading Bihar land papers
- Jamabandi and khatiyan records on Bihar Bhumi usually show area (rakba) in acre and decimal. Decimal is a fixed 435.6 sq ft everywhere, so it is the safest unit to compare.
- On the Chhapra scale, 5 dhur is exactly 435.6 sq ft, which is 1 decimal. On the Patna scale, 1 dhur is about 0.156 decimal.
- In parts of eastern Uttar Pradesh, katha and dhur are sometimes used as local names for biswa and biswansi sized parcels, so do not assume the Bihar value there.
- Values for Gaya, Bhagalpur, Purnia and Darbhanga are not in our data. Ask locally.
- Before a sale or partition, confirm the dhur size with the local amin, karmachari or circle office and match it with the decimal figure in the record.
